What do we know about electricity and circuits? What don't we know?
Can you describe the terms circuit, switch, series, parallel, AC, DC, battery, cell, buzzer, lamp, conductor, insulator?
Whats in the boxes? See if you can make something happen using the materials.
Week 1
Answer these questions using the following activities:
1. What is a circuit? What is the difference between a parallel and series circuit?
2. What is an electrical conductor? Give at least 2 examples.
3. What is an electrical insulator? Give at least 2 examples.
4. What is a switch?
5. Why can't you be killed doing these activities? (With the battery, wire, light bulb, switch etc)
6. What happens if you add another light globe to your simple circuit? Or add another battery?
7. Another thing you learned?
Week2
Answer these questions:
1. In pairs, complete the circuits worksheet. Just give a tick or cross for each if you think it will or won't light. For the circuits that won't light, explain why.
2. What are the symbols used to show a light/lamp, wire, motor, battery/cell, switch, buzzer.
3. Using the correct symbols, draw a diagram of a series circuit that has all of the above, with a switch to control each thing (motor, lamp, buzzer). Do it in your book or your computer.
4. Do the same for a parallel circuit.
5. Can you explain the difference between AC and DC electricity? Where would you most likely find them?
6. Find out how to make an electromagnet and make one.
7. Design a gadget of your choice and show the circuit diagram for it as well as the design.

A good interactive to explain a simple circuit.
Most of the symbols are here, with some good information about circuits.
